MAX11212

18-Bit, Single-Channel, Ultra-Low Power, Delta-

Sigma ADC with 2-Wire Serial Interface

General Description

The MAX11212 is an ultra-low power (< 300µA max

active current), high-resolution, serial-output ADC. This

device provides the highest resolution per unit power in

the industry, and is optimized for applications that require

very high dynamic range with low power such as sensors

on a 4mA to 20mA industrial control loop. The MAX11212

provides a high-accuracy internal oscillator that requires

no external components.

When used with the specified data rates, the internal

digital filter provides more than 80dB rejection of 50Hz

or 60Hz line noise. The MAX11212 provides a simple

2-wire serial interface in the space-saving, 10-pin µMAX®

package. The MAX11212 operates over the -40°C to

+85°C temperature range.
